I recall we had to hack the registry to send the warning to users when we rolled out XP. We DO want the warning to occur going forward as we roll out W7. Everything I've read about cached credentials seems to talk in circles around there being a problem, but nothing about how to send the users the old warning. Thanks!

Hi, We do not recommend modify registry. Modifying REGISTRY settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of REGISTRY settings can be solved. Modifications of these settings are at your own risk. And base on my experience, there is not configuration or settings on Windows 7 to turn on this warning. Thank you for your understanding.
